Ecology as an Operating Manual for Spaceship Earth Flashcards
Biome
A group of ecosystems that have the same climate
Carrying capacity
The band/zone of equilibrium between natality and mortality
The SIR model of pathological spread
- Susceptible
- Infected
- Removed
Ecology
The branch of biology that deals with the relations of organisms to one another and to their physical surroundings
Ecology might be perceived as the intersection between
- animal behaviour
- conservation
- evolution
- genetics
Organism
A single living thing
Population
A group of organisms of the same species living together
Community
A group of populations that live together
Ecosystem
Communities and their abiotic physical environments
Biosphere
All the biomed on earth: all the living areas of the planet
What is the type of growth that reaches carrying capacity?
Logistic
Describe immigration
When there are more species, fewer species are potential colonists
Describe extinction
When there are more species, competition leads to increased extinction
Larger, less isolated islands have
More species
The equilibrium number of species depends on
Area and isolation
